[TenTec] Orion, Eagle, and OMNI 7

[Richards]

I have several in the shack for Hi Fi and ham use, I have some old 
Realistic (RadioCrack) 10-band equalizers Cat. Co. 31-275 and 31-1989, 
and a Sansui GM77, and all of these can be had in good condition for 
under $50 on eBay if you shop carefully.  New ones by Behringer, or 
Technical Pro, or maybe Peavey can be had for around $99 or so. 
Sometimes you can use one channel of a stereo model on one rig, and the 
other on another rig, allowing for separate EQ of two rigs.

TenTec radios are cool because they sometimes have a LINE-OUT jack on 
the rear (typically on the octopus accessory ACC-1 jack cable) and that 
allows you to use the rig speaker, or an extension speaker, plus route 
the audio at Line-Level to the EQalizer and powered speakers, and even 
use the headphone jack separately and still have the audio routed to the 
LINE-OUT line level jack  (and maybe put your headphones into the final 
speaker/headphone device) - or - you can route the speaker out to the EQ 
and powered speakers, or the like, and you have some flexibility on 
where to put it.  I use the LINE-OUT to the EQ and then input that into 
a TimeWave DSP 599zx audio filter, and use its separate output to 
powered speakers and/or headphones.

AND, you can usually bypass the EQalizer if you like.

Hope this helps... I can do photos, too...  just ask.

Simple to deploy if you are using amplified speakers such as computer speakers or the popular small nearfield studio monitors.   I don't use one on ham radio, but my wife and I enjoy listening to old time radio programs, and we tailor the audio for best presentation of the speech frequency spectrum, and it makes a substantial difference.   She has partial hearing loss, so it really helps to tune the audio to her limitations.
